We used the polymerase chain reaction to clone two distinct 550 bp-long DNA fragments, Wc-I and Wc-II, of the gene encoding the Cryptospordium oocyst wall protein (COWP) of C. wrairi, which showed 98% identity to the C. parvum homologue. (eurekamag.com)

Over the course of six months wild filth flies were collected from traps left for 7-10 days in a barn with or without a calf shedding Cryptosporidium parvum Genotype 2 oocysts in diarrheic feces. (ajtmh.org)

Pigs, as other meat-producing animals, can become infected by the ingestion of oocysts that are shed in the environment by infected cats or by the consumption of cysts present in tissues of infected mammals, commonly small rodents. (semanticscholar.org)

The number of oocysts excreted could not be correlated significantly with farm type or farm management but depended on the floor type which influences the infection pressure, on the age of the calves and the time after rehousing. (springer.com)

Bi-oo-cyst virucide bactericide fungicide coccidiacide effective against excreted endoparasites including unsporulated oocysts & other worm eggs bi-oo-cyst is the first disinfectant designed to be a powerful, DEFRA approved virucide, whilst also being effective against endoparasites especially oocysts. (solwayfeeders.com)

Bi-OO-Cyst is the first disinfectant designed to be a powerful virucide, whilst also being effective against endoparasites, especially coccidial oocysts which are microscopic parasites that infect the gut and result in Coccidiosis disease, this of course is fatal to poultry if not treated immediately.

Oocysts of the malaria parasite form and develop in close proximity to the mosquito midgut basal lamina and it has been proposed that components of this structure play a crucial role in the development and maturation of oocysts that produce infective sporozoites. (biomedcentral.com)

These observations not only highlight the risk that aquatic biofilms pose in regards to Cryptosporidium outbreaks from water distribution systems, but further indicate that even simple biofilms are able to stimulate oocyst excystation and support the extracellular multiplication and development of Cryptosporidium within aquatic environments.

The overall goal of the project was to develop probes to identify and assess the roles of proteins, carbohydrates, and lipids in the integrity and resistance of the oocyst wall to disinfectants. (booktopia.com.au)

The results demonstrate that either a DE precoat filter or a perlite-sand filter can improve the efficiency of removal of microspheres and oocysts from swimming pools over a standard sand filter under the conditions studied. (environmental-expert.com)

Recipient(s) will receive an email with a link to 'Total and infectious Cryptosporidium oocyst and total Giardia cyst concentrations from distinct agricultural and urban contamination sources in Eastern Canada' and will not need an account to access the content. (iwaponline.com)

Laminin was also detected on the outer surface of the oocyst capsule, incorporated within the capsule and associated with sporozoites forming within the oocysts. (biomedcentral.com)

Thereafter, laminin secreted by midgut epithelial cells and/or haemocytes, binds to the outer surface of the oocyst capsule and that some passes through and is incorporated into the developing oocysts. (biomedcentral.com)

These microscopy observations were further supported by flow cytometric analyses, where excysted oocyst populations were detected in 1, 3 and 6 day-old Cryptosporidium-exposed biofilms, but not in biofilm-free controls. (edu.au)

Genes differentially regulated during the ookinete-to-oocyst transition may determine the development of the parasite within the mosquito host, as well as, participating directly in parasite/mosquito interactions. (imperial.ac.uk)
